Top 20 2007 Chevrolet Silverado 1500 Questions & Answers

What is the code ? Circuit wiring problem ,maybe !

There is a button located around the opening of the cars hood area that is pushed down when the hood is close, or around lock latch that is depressed when closed.

You actually provided a very good description of the issue. You didn't mention any check engine light on so I am assuming it is not illuminated. Based on your description I would focus on the park/neutral safety switch located on the transmission just below the shift cable attachment at the transmission. Start there. Good luck.

There aren't any, most likely. Most vehicles since 2000 don't have grease fittings.

parts store can tell what the code is or dealer..

Have the alternater checked. The voltage regulator may be sticking and leaving an open circuit.

This is a bad connection on the throttle body.Look at front of motor at the passenger side of the throttle body is a set of wires thats where the bad connection is. First disconnect the connector and put dielectric grease on it and see if that helps if not then replace the connector with a new connector and your problem should be gone.

Check the link. Should be okay. https://www.google.com/search?q=Chevy+Silverado+4L60E+transmission+years+used ..

first buy a DMM meter ,spend $15 and end working blind. the battery and alternator are easy to test and for sure loss of any kind of DC power easy to find using the meter (ASK HOW) K2500 pickup or Suburban???? no told and wiring not the same. no engine told and that too sets wiring. OMG 6 engines 2 diesel. elaborate NO POWER< means head lamps dead? what? and stayed on? means what.? STEP #1 alternator work , battery NEG LUG OFF FIRST or you will blow the 100amp main fuse. doing this ALL WRONG and if a fuseable link, can be hard to find, as others say, not me. never ever connect any main battery backwards or you will blow up very expensive electronics, best I can tell is first failure was the fuse even those kinda hidden fuses called Fuseable links. fuses are first on cars, of head lamps dead and park lamps dead this is first, head lamps work keyon , or off. so is first thing to check with DC POwer loss, (NO POWER"?) if battery is 12vdc then the power is not lost but fuses are blown for sure. head lamps are a safety devices that work even no key in hand. the under hood box has a fuse marked Lighting, if blow HL are dead just below Lighting fuse is battery bus bar fuse. <<< blown? the only hard thing THIS CAR,is the online books stink back in 1992 no digital books then so most cars nobody was willing th scan 500page service manuals. (nor me) so only sparse information exists. (join k2500 real forums? Chevy)\ this truck does have (did new) 4 x fuseable links, 1 for alternator but only that blown kills alternator and runnining engine battery is not 13. to 15vdc so the battery goes dead fast 1/2hour fast. below 13vdc the alternator is dead or fuse link ALT is blown there are more LINKs to blow 3 more. others kill the cab or engine bay fuse boxes dead so all boxes must be check for lost of 12vdc raw DC power. head lamps parking lamps. to top the list and more, check all things DC power, even radiol the list of things dead tells you what fuse box is dead. hope that helps in any way. regards.

A parking brake (informally known as "emergency brake" or simply "e-brake") is a secondary brake system that uses brake cables to engage the rear brakes rather than the using the hydraulic brake system which actuates both the front and rear brakes. The brake cables are pulled by a ratcheting mechanism inside a cabin which can be a pull lever or a push pedal. In either case the mechanism must be able to release the cable tension. Although rare, a problem in this mechanism could prevent the ratchet from disengaging and in turn keep the parking brake engaged. A much more common problem however is with the cables or brakes themselves. Rust and corrosion that accumulates over time can cause the moving parts to bind and not release from their engaged position. To resolve, the binding parts must be moved back into their original resting position manually and then replaced with non-rusted/corroded parts. In some extreme cases it may be necessary to actually cut through a brake cable in order to release tension and make repairs.

The parking bake assembly return spring may be broken. Is it possible to manually lift the pedal up while releasing the brake? The cable could be seized not allowing the pedal to retract.

Press the power button. Access the clock via the menu button. Finally press the dash buttons that are located right under each display to set the hour, minute, month, day, and year on the 2013 silverado.

Should be on the firewall under the hood. Behind the dist. Cap or in that area.

4.3L = .045, / 5.0L & 5.7L = .035

You replaced the SDM , was it programmed ?

Hi, if you performed these tasks and still cannot start the car, please double check that you're using all products from the manufacturer of the car (or affiliated). This type of thing happens with printers...where the main device won't work if it senses any 3rd party or unauthorized components. You can try to call your local dealership to see if your car is built like this. Thank you.

DTC P1637 The powertrain control module (PCM) / engine control module (ECM) uses the charge indicator control circuit, and the generator 2 turn on signal circuit on diesels with dual generators, to control the generator(s). A high side driver within the PCM/ECM allows the PCM/ECM to turn the generator ON and OFF. When generator operation is desired, the PCM/ECM sends a 10-11 volts-volt signal to the voltage regulator via the generator turn on signal circuit. This causes the voltage regulator to begin controlling the generator field circuit. Once the generator is enabled by the PCM/ECM, the voltage regulator controls generator output independently of the PCM/ECM. Under certain operating conditions, the PCM/ECM can turn OFF the generator by turning OFF the voltage on the charge indicator control circuit. The PCM/ECM has fault detection circuitry which monitors the state of the charge indicator control circuit. If the fault detection circuit senses a voltage other than what is expected, the charge indicator will turn ON and this DTC will set. The voltage regulator also contains fault detection circuitry. If the regulator detects a problem, the regulator will ground the charge indicator control circuit, pulling the voltage low. This also causes the charge indicator to turn ON and the PCM/ECM to set the DTC. What engine is in your truck ? DTC P1638 The powertrain control module (PCM) uses the generator field duty cycle signal circuit to monitor the duty cycle of the generator. The generator field duty cycle signal circuit connects to the high side of the field winding in the generator. A pulse width modulated (PWM) high side driver in the voltage regulator turns the field winding ON and OFF. The PCM uses the PWM signal input to determine the generator load on the engine. This allows the PCM to adjust the idle speed to compensate for high electrical loads. The PCM monitors the state of the generator field duty cycle signal circuit. When the key is in the RUN position and the engine is OFF, the PCM should detect a duty cycle near 0 percent. However, when the engine is running, the duty cycle should be between 5-100 percent. The PCM monitors the PWM signal using a key ON test and a RUN test. During the tests, if the PCM detects an out of range PWM signal, DTC P1638 will set. When the DTC sets, the PCM will send a class 2 serial data message to the IPC to illuminate the charge indicator.
